TOBACCO-PIPE.

Specification of Letters Patent.

Patented Dec. 8, 1914.

Application filed September 29, 1913. Serial No. 792,492.

To all whom it may concern Be it known that I, JoNEs II. K nk, a citizen of the United States, residing at Fort Snelling, in the county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Tobacco- Pipes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in tobacco pipes.

One object of the invention is to provide a simple device of this character which can be quickly and easily cleaned.

Another object is to provide a device of this character which can be readily taken apart when it is desired to thoroughly clean the entire pipe.

Other objects and advantages will be apparent from the following description, when taken in connection with the accompanying drawings.

In the drawings: Figure 1 is a vertical longitudinal sectional view through a pipe made in accordance with my invention. Fig. 2 is a side elevation of the stem and cleaner removed. Fig. 3 is a perspective view of one section of the cleaner. Fig. 4: is a vertical transverse sectional View on the line 44 of Fig. 1.

Referring particularly to the accompanying drawings, 10 represents the bowl of the pipe, and 11 the stem portion thereof. Formed longitudinally in this stem portion is a bore 12, the outer portion of which is slightly enlarged as indicated at 13, while the opposite end is disposed directly under the center of the bowl and communicates therewith by means of the vertical passage 14:.

Disposed in the bores 12 and 13 are two longitudinally grooved sections 15 which when placed together form a tube, the end below the opening 14 being provided with a plurality of openings 16, while the opposite end of this tube is slightly enlarged as indicated at 17 and provided with threads to be received in the threaded bore 18 of the bit 19 of the pipe. The portions 15 of the tube are slightly resilient, and have a nor mal tendency to spring away from each other as clearly shown in Fig. 2, but are held in close engagement by reason of the fact that this tube snugly fits within the bore 12 of the pipe.

When the parts are assembled, as shown in Fig. 1, the smoke enters the tube by means of the openings 16, and travels through the tube to the bit as will be understood. When it is desired to clean the pipe, as in removing an obstruction while smoking, the bit is simply pulled away from the stem 11 thus drawing the cleaning tube with it. As the inner ends of the sections 15 are withdrawn from the bore, they spread apart, providing ready access between them to permit cleaning. This can be easily accomplished by simply shaking the stem and cleaner. When the pipe is to be thoroughly cleaned, the sections 15 can be unscrewed from the stem and all of the parts washed in hot water or any suitable substance.

The enlarged portion 17 is also longitudinally divided, and each portion has in its flat face a pin 20 and a socket 21. The pin of one portion engages in the socket of the other portion and holds the parts in proper position for the threads to engage in the ore.

It will be noted that as the tube is withdrawn from the bore of the stem of the bowl, the tendency of the sections to spring away from each other results in a scraping engagement thereof against the walls of the bore so that the bore is cleaned.

IVhat is claimed is In a tobacco pipe, a bowl having a stem portion provided with a longitudinal bore terminating at one end under the bowl and communicating with the interior thereof, the opposite end of the bore being slightly enlarged, a longitudinally divided sectional tubular member having one end slightly onlarged to fit within the enlarged bore, the opposite end of the tubular member being provided with openings registering with the opening of the bowl, the sections of the enlarged portion of the tubular member being threaded, said threaded sections having intel-engaging lugs and recesses on their abutting faces, the bit of the pipe having a threaded bore to receive the enlarged portion of the tubular member, the smaller por- In testimony whereof, I aflix my signations of the tubular member being resilient ture, in the presence of two witnesses. and arran 'ecl to sprin away from each T other to pr ocluce a cont ct between the see- JONES KIRK 23 tion and the walls of the longitudinal bore Witnesses:
